Write difference between diffusion and osmosis

diffusion is the movement of molecules from the region of higher concentration to that of lowers and there is no involvement of any semi permeable membrane .... on contrary osmosis refers to the diffusion of water through a semi permeable membrane


The Brainliest Answer!
Osmosis is the diffusion of water across a membrane against the gradient. this means that water molecules diffuse across the membrane from a low ionic strenght to high ionic strenght containing solutions.

diffusion is where molecules travel across membranes along the gradient. it means that molecules will travel across a membrane from a solution of higher concentration to a solution of lower concentration.

diffusion also includes diffusion of water ie osmosis. therefore osmosis is a part of diffusion. whenever molecules diffuse across a membrane, water also diffuses across the membrane in the opposite direction that the molecules diffuse across.

Diffusion is the movement of molecule from a place of high concentration to a place of low concentration through a semi-permeable membrane. 

Osmosis is the movement of molecules from a place of high water concentration to a place of low water concentration through a semi-permeable membrane. 

Thus the only difference is that Osmosis is to do with water.
